Light: Full sun to partial shade; morning sun with afternoon shade is best in Phoenix’s intense summer heat.
Water: High water needs in Phoenix; water deeply and frequently enough to keep soil consistently moist during active growth. Reduce watering substantially during winter dormancy.
Soil: Rich, moisture-retentive soil with good drainage; amend desert soil generously with compost and mulch to cool roots.
Mature size: Typically 3–6 feet tall and 2–3 feet wide initially; rhizomes gradually form wider colonies.
Bloom: Late spring through fall, with repeat flowering under warm, moist conditions; extreme heat or drought may reduce blooming.
Evergreen / deciduous: Herbaceous perennial; foliage dies back with frost but may persist through mild winters in protected locations.
Growth rate: Fast during warm weather with adequate water and nutrients.
